LAMP SHADE.

Application led January 16,1928. Serial No. 247,025.

The present invention relates to lamp shields or shades adaptedparticularly for use in association with electric lamp globes, its mainobject being the provision of a shield of flexible translucent material,which, when not in use, would remain in fiat position.

A further object of the present invention is ythe provision of a lampshield, which, when vnot in use,would remain in flat position, and whichcould-be suitably formed preparatory to its positioning upon the lamp.

`lith the above general objects in view and others that will appear asthe nature of the invention is better understood, the same consists .inthe novel construction, combination and arrangement of parts hereinaftermoreV fullydescribed, illustrated in the accompanying drawings andpointed out in the appended claims.

In the drawing forming a part of this application and in which likedesignating characters refer to corresponding parts throughout theseveral views,

Fig. 1 is plan elevational view of the device in its inoperativecondition;

Fig. 2 is an enlarged perspective view of the shade in its'operativeposition;

Fig. 3 is a top elevational view of the device when the same remains inan operative position; and A Fig. 4 is a cross-sectional view on line-Mof Fig. 3.

Referring to the drawing in detail there is shown a shield 1() which hasa substantially rectangular form as seen Von Fig. 1. Said. .shield ismade of colored Celluloid or any other flexible and translucentmaterial, such as parchment or the like.- -At its upper edge, andcent-rally thereof, said shield 10 is provided with hinge 11, which ismade of a single plate 'and folded to'provide two leaves `within whichsaid shield 10 is clamped. Rivets 12 passing through the two .leaves ofsaid hinge and the clamped portion of the shield, hold said hinge inpermanent position upon said shield. Atthe central portion at the upperedge said hinge 11'is cut away as at 13 effecting a pair of loops 14which pro]ect beyond the upper edge of the shield '10.

The mechanism for holding the shield 10 in its operative position andfor mounting the shade upon the lamp comprises two flexible wires,generally indicated by 15, which are suitably formed and arranged. Eachof said wires has'an arcuate portion 16, at their outer ends saidarcuate portions 16 terminate in U- shaped loops 17 radially positionedwith respect to said arcuate portions 16 of wires 15. rhe outer sideslSof said U-shaped loops 17 at their outer terminations are outwardly bentto provide curved projections 19, which, 1n cooperation with theremaining portion of said outer sides 1S affect seats 2O for thepurposes hereinafter stated.

The inner ends of said arcuate portions 16 of wires 15 pass through andare pivoted within loops 14 of the hinge 11. Thereupon said inner endsare bent inwardly forming legs 21, which are in radial juXta-positionrelative to their respective arcuate portions 16 of wires 15. Thereupon,each of said wires 15 is formed into loops 22 which immediately projectfrom said legs 21 and which are formed in the opposite directions toprovide a clamp generally indicated by 23`on Fig. 1. Said clamp isadapted to fit the periphery of lamp socket 24, and when said clampremains upon the lamp socket 24 its component sections 22 will remain insubstantially parallel relation with their respective arcuate portions16. The ends of said loops 22 are outwardly bent and in addition areupwardly turned as at 25, as clearly seen on Fig. 2, to facilitate theinsertion of the lamp socket 24 within the clamp 23, or morespecifically within loops 22. To maintain the two wires 15 in permanentrelation with each other leg portions 21 of said wires 15 are joined bybridge plate 26, so that said wires 15 operate in unison and 'constituteone single mechanism for the purposes hereinabove indicated.

Shield 10 at its upper corners is provided with metallic eyes 27 withinwhich the outer ends of sides 18 of loops 17 are receivable, and

,normallyY when the lamp shade is in its operative position, said eyes27 are adapted to remain in seats 2 0. It is observed that said seats 20are on an outer peripheral line with the .arcuate portions 16 of wires15, so that when said eyes 27 are upon said sides 18 and rest in seats20, the'upper edge of said-shield 10 will snugly lit the outer peripheryof arcuate portions 16 of wires 15. Since said wires 15 are of resilientand springy nature, and particularly through the action of sides 18 ofloops 17 which have a tendency to draw shield 10 outwardly, said shield10, when in the operative condition, will be held in stretchedcondition, presenting a uniform and neat appearance. Curved projections19 will remain outwardly of said eyes 27'aiid are intended forpreventing slipping of said eyes 27 from their respective seats QOavhensaid shield remains in stretched operative position vupon said Wires 15.

YYIt is further noted that tions 16 of Wires 15 constitute inconjunction with each other asemicircle Which'shape Will l "be impartedto shield'10 when the saine remai'iisiii operative association VwithWires 15.

` Y It is further'observed that since the actionV of Wires exert theirgreatest influence upon the-upper end of said shield 10, there beingiiodirect stretching or influence of Vsaid'wires 15at the lowerv end ofsi id shield 10,5said lower end of said shield'l() iviil'have a tendencyto flare out, by virtue of Which action the entire shield ivillassumea'frusto-vconical appearance, as seen oii'Figs.' 2 and ,3. Y

vilhcn,endszl-B of-loop 17 are Withdrawn from eyes 27, lshield 10 Willassume flat post 1 tion, illustrated on Fig. 1 and indicated bydotted'iines on 'Fig'. 3, and thereupon Wires 15, including all of theirVformations herein# Vabove"described, may he angularly shifted inrespect of said'shield 10 upon hinge 11 to assume various' positionswithrespect to said 'shield 10. Fig. 1 illustrates two of the possiblepositions of said mechanism formed by A Wires 15, one position beingshown in full lines Where said wires'remain upon the plane of saidshield 10. and another position, illustratedV by dotted lines showsrsaid Wires as being'. folded upon Vthe underfaceJ 'of Said shield 10, jii Y.

By virtue of the feature whereby both the l shield 10 and its mechanismmay be heldl fiat when the device is iii an inoperative condition, thedevice Will occupy the minimum of space, Which fact Will facilitate thetransportation in quantities. Note is. made o f the fact that hinge 11is slightly benton ho 1izontal plane,

Y butinot to a degree toV form a true continuaV periphery of shield 10When the tion of 'the Y saine is in operative condition. VThis arrange-Y ment-Will no'tinterfere With shield v1() in as-V fsuming theoperativeposition as shown onA Fig'. 2 and at the same time Will permit a iiat llposition shown on Fig.V livhen said shield'is released from theengagementby sides 18Y ofv 16.0155 17- i While there. is describedhereina preferred embodiment of lthe present invention, it isnevertheless to be understood that minor i changes may vbe madeVVtherein, `Without desaid arcuate por-'1 parting from the spirit :andscope of the int vention as claimedl t Y v -What I claim as new is:
